CLUTCH IN MACHINES FOR PACKING- ILOTJ'IIR..y

Specification of Letters Patent No. 12,107, dated December19, 1854.

To all whom t may concern .f

'Be it known that. I, SAMUEL4 TAGGART, of Indianapolis, in the county of Marion and State of Indiana, have. invented certain new and useful Improvements in Machines, for

Packing Flour ;A and I do hereby declare y that the following is a full, clear, and eXact useful improvementsn machines forpacking' flour, and consists, in the employment or use of a clutch constructed in a peculiar y pulleys (72.), (7L), at. theupper part ofthe:

manner, as'will be hereafter shown and. described, whereby motion 1s communicatedto the screw or packing shaft, and also a cer tain amount, of pressure given to the screw.

'Ilo enable others skilled in the art to make -and use my invention, I will proceed to de scribe its construction and operation.

A, represents the flour chest which may be of an inverted conical shape having; its lower end provided with a lianch (a), the use of which will be shown hereafter.

C, is the/packing shaft which passes ver tically through the flour chest B, and having at its lower end a spiral flanch or screw D, the diameter of which is of suchasize as to fill the lower end or discharging aperture of the iour chest. The upper end of the packing shaft C, is inserted in a head E, which works or slides freely up and down in a frame F, at the upper part of the frame A. The upper part of the packing shaft passes entirely through thevhead E, and turns within it, and has a pin (b), passing through it just above the head.

Gr, is a clutch formed of a hollow cylinder or thimble Gr', fitted in the frame A, so as to rotate, and having a horizontal beveled wheel I-I, at its upper end, which wheel H, gears into a beveled wheel I, hung at one end of a driving` shaft J K, is a collar which is fitted horizontally within the cylinder or thimble, and so attached to it as to slide or play vertically a short distance, but at the same time connected to the cylinder or thimble so as to turn wit-h it at all times,

, see Fig. 2,. in which the collar is showin con-v l nected to the cylinder or thimble by d`ove.-

tail. recesses (c), (c), which fi't over correspending projections. (d), (el), on the inner sides of the cylinder orv thimble.

The shoullders (af), (a) (b), (b) between which'. ille collar plays vertically are shown in.

iv. l.V l

'.blhe packing shaft, C, passes'v through the,

y cylinder of thimble. Gf', and. coll-ar. K, and' jhas spiral ianches or ribs, (e), (fe), upon it ,within the cylinder o-r thimble.v On the inner periphery of the collar K, there, are two ,studs or nibs f), f), which; bear againstvv the spiral flanches. or ribs- (6) (e), on, the. i

packing shaft, as shown Fig.y 2;. In Fig.. l, they are not seen as the plane off section cuts, ofi" one and thev .other is. behind the packing shaft.

To the upper end ofthe head E, a cordJ g),l is attached, said; cord passes over frame A, and is attached to a` baror weight.v

, L, at the side ofthe frame,l A.

M, isa ylever at the` upper part of the the. upper end of this lever is. connected: a`

bary (j), the outer end. of which is perdio,-

rated. with a hole ,throughwhich. arod; (113) ,frame A, and havingl its. fulcruni at (41) to;

on the cord (g), passes, the rod, (Ja)z,ghaving a hook or eye (l), at each end which cannot pass throughl the holer in the barv(j)-4 .Att

the lower end of the lever M, there is a catch (m), the use of which will be hereafter shown.

O, is a spring which acts against the lower end of the lever M, and keeps it out from the side of the frame A.

P, is a plat-form attached to sliding bar Q, which is placed vertically against a stationary beam or stud R, secured within the frame A. The sliding bar Q, is moved up and down by a lever S, which has its fulcrum at (n), in the beam or stud R. The outer end of the lever S, is held down when desired by a pawl T, attached by a pivot (o), to the beam or stud R.

Operation: The spiral flanch or screw D, previous to operating the machine, is at the bottom of the flour chest B, and iills the discharging aperture, the packing shaft being held up by the catch (m),r which is underneath the head E, see red lines Fig. l. y The v flour chest B, is now filled, and the barrel to be packed with Hour, represented by"U, is placed upon the platform P, which is raised by depressing theleve'r S, the upper end of the barrel fitting over the discharging aperture of the our chest and bearing against the lanch (a), the barrel being sustained in this position by the pawl T, the outer end 0f which rests against the outer end of the lever S. The lever M, is now operated by depressing the bar or weight L, and the catch (m), is thrown out from under the head E, the packing shaft then falls by its own gravity, and the screw D, reaches the bottom of the barrel. Mot-ion is now given the driving shaft J, and the cylinder or thimble G', is made to rotate by the gearing H, I, and as the collar K, turns with the cylinder or thimble, the studs or nibs (f), (f), on the inner periphery of the collar act against the spiral lanches or ribs (c), (e), on the packing shaft C, and cause it to rotate, said packing shaft, as it rotates, ascending upward in consequence of the screw D, which packs the flour in the barrel as it ascends. A certain pressure is given the screw in consequence of the studs or nibs (f) (f), of the collar acting against the spiral flanches or ribs (e), (e), and the packing shaft, the ribs and spiral flanches having a tendency to bear the packing shaft downward. The spiral flanches of course move upward within the cylinder or thimble Gr, and cause the collar to bear against the upper shoulders (a), in the cylinder or thimble, and when the lower end of the spiral i'lanches just pass above the studs or nibs (f), (f), on the collar K, the catch (m) at the lower end of the lever M, passes underneath the head E, and the collar K, falls upon the lower shoulders (5'), in the cylinder or thimble G', and the packing shaft ceases to rotate, the cylinder or thimble still rotating, its motion being constant. The

barrel is now removed by throwing the pawl T, out from the lever S, which causes the platform P to descend. A fresh or empty barrel is then placed upon the platform, and the operation above described, repeated.

The above machine works well in practice, and is .portable and economical to manufacture. The spiral flanches or ribs (e), (e), render the weighting of the shaft, to obtain the necessary pressure upon the screw, unnecessary, and the manner of raising and lowering the barrel works far better than the lever which is now employed, and which acts upon' the barrel with a curvilinear friction, and requiring much space for its operation.

I do not claim the spiral flanch or screw D, separately for packing flour, for that has been previously used, neither do I claim a clutch for communicating mot-ion to the packing shaft, irrespective of the peculiar construction and arrangement of the one herein shown and described.

What I claim therefore, and desire to secure by Letters Patent, is

The employment or use of the clutch G, formed of a cylinder or thimble Gr, provided with a collar K, as shown, and having studs or ribs (f), (f) on its inner periphery, which studs or nibs act against spiral flanches or nibs (e), (e), on the packing shaft C, said cylinder or thimble having a constant rotating motion given it. The several parts of the clutch being'otherwise constructed, arranged and operating in the manner and for the purpose as herein set forth.
